Designing processes - EMC Community Network

Deploying the Application
which the performer is referenced. It also enables you to replace a performer globally throughout a
process with a new performer without making a replacement at each activity the performer is used.
Note: A process parameter is specific to a process. Therefore, process designers must update the
process parameter for each process, even if two processes have a process parameter with the same
name.
Updating process data
To modify an SDT in any of the following ways, delete the SDT (from the target environment) before
installing your application into the production environment:
• Remove an attribute.
• Decrease the length of a string variable.
• Change a repeating attribute to a non-repeating attribute.
• Change the data type of an attribute.
To update an object type in any of the following ways, drop the object type from the production
environment before installing your application into the production environment:
• Remove an attribute.
• Decrease the length of a string variable.
• Change a non-repeating attribute to a repeating attribute.
• Change a repeating attribute to a non-repeating attribute.
• Change the data type of an attribute.
Versioning the process template
If the application you are deploying replaces existing process templates that have running workflows,
version the process template. Versioning the process template enables existing workflows to continue
to function after the application updates the process template. To version the process template, do the
following:Existing workflows complete by using the older version of the process template, while new
instances of the process template use the new version of the process template.
1. Import your updated process template into your project and set the installation options of the
process template to VERSION.
2. Install the DAR file created from this project into your target repository.
Overwriting an existing process
When deploying an application from one environment to another, do the following to overwrite
an existing process (rather than versioning it).
1. Uninstall the process templates that will be overwritten. This halts running workflows.
2. Reinstall the process template, selecting to abort all running workflows. This ensures that there are
no running workflows when the process template is overwritten.
When to use Composer
Do not use Composer as a development environment to modify your processes. Use Composer only to
archive and install (including the use of installation parameters). Use the appropriate tool in xCP to
make changes.
